They are aware of it, otherwise the filters would not have been introduced with Pro Pack for P4, they did announce I think that they were working on this for a future release, a Poser 5 Pro Pack I suppose. It's unfortunate that if they're as desperate as intimated that they didn't consider this as a greater source of revenue and aim at pro-level as well rather than leave it to a "later date" when they might not even be around. Indication from Cooper's own comment is that they needed the money from this release to survive, that survival may have been greatly influenced by the current situation and the lack of hi-end support. Time will tell of course, but I personally think it was a serious error.
